I have googled for quite a while, and have not found the pinout on the microUSB port. I really want to know if there is any way to get analog output from that port like my old G1. It would be nice to have one port for charging and audio (for cars, docks, and boomboxes).

Thanks for that. But I wonder how that port will provide audio with something like this?

ok, I am just curious, but you dont want to use the audio output on the top of the phone just to have an all in one solution, correct? Because I have no clue what would happen hooking that adapter up, curious though.
It has to be built into the port as well as the software to control it. I've got my money on it not working, since it's not supported by the phone. HTC ditched the USB headphones a while back because everyone complained about having to use special headphones and adapters, hence why they all have standard headphone jacks now.

Exactly. Having a dock or boombox that would be plug and play would be nice. I'm actually considering something for the car that would replace a head unit. Maybe there would be a way to snag the digital audio from the HDMI port? Digging continues.
Worse case scenario, I use the USB port for power and bluetooth the audio.
I dont think it is possible through hdmi without a digital to analog converter, which are rather expensive. The hdmi out is pure digital goodness.

ORLY?
Lol, I guess for me 50 bucks is rather expensive to free up a wire. But to each his own

Have you seen what Apple charges for white cables? LOL! I think $50 works.
Lol, fair enough
HTC ExtUSB Micro?
I am looking for the same info.
Is the micro usb port on the evo just a standard 5 pin only?
The mini usb on the hero was the non-standard HTC ExtUSB with 11 pins. I loved this because I could make my own docks that included power and audio with only one plug.
Maybe the HTC micro b is analogous? HTC ExtUSB Micro?
I dont think so, it's only 5 pins. And I think the only reason HTC had the 11 pin was to provide the proper support for audio out. Since the evo has a 3.5 mm I dont think it is even possible to do that.

And how exactly do you intend to convert the HDMI to a digital RCA or TOSLINKi nterface as that box requires? Oh, another $50+ box? Yeah, that's what I thought. So, $100 or a cable that looks "silly". I know where my money would go...
The Samsung Fascinate has this audio/usb option. Their docking station has a micro-usb plug and then a USB (power) jack and a standard audio jack out. So it doesn't require any special decoder, there must be audio out pins just like in the iPhone/iTouch?
Take a peek at this photo of an Evo's circuit board. Specifically, the solder points for the microUSB port (including the ground/anchor points):
http://guide-images.ifixit.net/igi/22dlA5ZuptWCyvTX.huge (from http://www.ifixit.com/Teardown/HTC-Evo-4G-Teardown/2979/1 )
Count 'em. Eleven, just like extUSB on the Hero & other HTC phones. Looks like the Evo has what could legitimately be called a "HTC micro-extUSB" port, and not merely a standard "micro-USB" port.
Now... good luck trying to find a CABLE with all 11 contacts and wires on it. If it exists, Digikey probably has them... but god only knows where that needle might be in their million-part haystack (anyone who's ever tried finding a specific connector, even a common one, at digikey.com if you don't know its exact OEM part number knows the joy I'm describing...)
Chances are, there's a (~2.7v) serial UART sitting on two of those pins, too.
(update: found a few references to "Micro extUSB" with regard to the Desire, including http://windowsmobilesmartphone.forumcommunity.net/?t=39522724 )

Isn't that the HDMI connector?

Nope. It's definitely the Micro USB connector. I know this is an old thread, but I've been trying to do some research on this port in hopes of hacking my own car dock.
I've found some additional information on this Micro ExtUSB™ port. The HTC Incredible uses it for its TV Out port. See this Thread on AndroidForums. There's even a special cable for the Incredible at HTCPedia. I'm very tempted to buy the cable to use it as a sort of breakout box to experiment with this port.

I believe your looking at the micro hdmi port, the usb is indeed 5 pins.
I'm pretty certain it's just a standard 5-pin MicroUSB port. Just shining a flashlight into the port, I only see 5 pins.
It would be really nice if there was a standard connector that supported power, USB, audio, and some sort of control bus. The Apple dock connector is a bit big, but it allows for a lot more than microUSB can do. Though I guess it could be done over USB if there was a standard for it.
Is it hard for anyone else to use any other USB cord on the galaxy nexus? It feel like the connector gets caught on something and it won't go into the port. I am using the HP TouchPad USB cord if anyone really needs to know. It is a really irritating problem since I would rather use my longer micro USB cable rather than the short one that comes in the box. Can anyone provide any insight or something? What is the cord getting caught on? Should I be worried because I heard that the USB port has some problems. Thanks.
Anyone know where I can to buy a "usb male" to micro usb female cable/ adaptor?
I have something I want to try, but I would need one of these if possible.
Any ideas?
Thanks!

What would you want to try with that?
Are you referring to something like this:
ebay.com/itm/Hot-Mini-A-5P-5Pin-USB-Male-To-Micro-B-5P-5Pin-USB-Female-Extension-Data-Cable-/290699800110?pt=PDA_Accessories&hash=item43af0eee2e
only then with the full type-a plug on the male end?
I thing he means for Micro USB otg cable. You can get them for a dollar on Ebay.

No I mean a normal (not otg) that has a full sized usb male side to a micro usb female side.
Oh well I guess they don't exist.
you can always buy the two cables from a thrift store and then splice the cables yourself.

So are usb cables just connectors? Like can I just wire each pin to the exact opposite pin? Or is it more complex than than?
